/domains/{domain}/rules/error-page/
 
curl --request GET \
  --url https://api.nsin.ir/domains/example.com/rules/error-page/ \
  --header 'Authorization: Bearer <token>'

Controls what visitors see for selected status codes — the NSIN branded page, your own HTML, or the origin’s own response passed through untouched.

Returned in evaluation order. Requires domain.view.

Authorizations

Section titled “Authorizations ”

Parameters

Section titled “ Parameters ”

Path Parameters

Section titled “Path Parameters ”
domain
required
string

The domain name (for example example.com) — not a numeric id.

Example 
example.com

Responses

Section titled “ Responses ”

200

Section titled “200 ”

Error page rules.

Media type application/json
Array
object
id
integer
domain_id
integer
record_id

Deprecated single-record scope. Prefer record_ids. Absent for zone-wide rules.

integer
record_ids

The proxied DNS records this rule applies to. Empty or absent means zone-wide — every proxied record of the domain.

Array<integer>
type
string
Allowed values: cache drop redirect rewrite waf captcha rate_limit bot_route origin_pool origin_route fingerprint error_page
enabled
boolean
priority

Evaluation order; lower runs first. Defaults to 100.

integer
host_pattern

Optional hostname filter. Empty means the rule is not host-scoped.

string
host_match_type

How host_pattern is matched. The empty string means “no host filter”, and is the only valid value when host_pattern is empty — the two fields are set and cleared together.

string
Allowed values: "" exact wildcard regex
action_mode
  • enforce — the rule acts (block, redirect, challenge, …).
  • dry_run — the rule matches and is logged as “would have acted”, but the request reaches the origin unchanged. Use it to test a rule safely.

Not every rule type honours this; cache ignores it.

string
Allowed values: enforce dry_run
created_at
string format: date-time
updated_at
string format: date-time
path_match_type

How path_includes and path_excludes are interpreted.

string
Allowed values: wildcard regex
path_includes

Paths the rule applies to. Defaults to ["/*"] — everything.

Array<string>
path_excludes

Paths carved back out of path_includes.

Array<string>
mode
  • nsin — the NSIN branded error page.
  • custom — your own HTML, from content.
  • origin — pass the origin’s own response through untouched.
string
Allowed values: nsin custom origin
codes

The status codes this rule covers.

Array<integer>
content

Status code (as a decimal string) → HTML. The key "0" is the fallback used for any covered code without its own page. Only populated when fetching a single rule — the list endpoint omits it.

object
key
additional properties
string
content_codes

Which codes have HTML, ascending (0 first when present). Always populated, including in the list response.

Array<integer>
content_bytes

Byte size per entry in content. Empty on the list endpoint.

object
key
additional properties
integer
Example 
[
  {
    "type": "cache",
    "host_match_type": "",
    "action_mode": "enforce",
    "path_match_type": "wildcard",
    "mode": "nsin"
  }
]

401

Section titled “401 ”

Missing, malformed, revoked or expired API key — or the owning account is inactive.

Media type application/json

The single error shape used by every endpoint.

object
error
required

Human-readable description of what went wrong.

string
Examples
Example invalidKey 
{
  "error": "invalid API key"
}

404

Section titled “404 ”

No such domain, or your role on it does not permit this operation. The rules endpoints deliberately answer 404 rather than 403 for an insufficient role, so they never confirm that a domain exists to someone who cannot use it.

Media type application/json

The single error shape used by every endpoint.

object
error
required

Human-readable description of what went wrong.

string
Examples
Example notFound 
{
  "error": "not found"
}

429

Section titled “429 ”

The key exceeded its request budget (300 requests per minute by default).

Media type application/json

The single error shape used by every endpoint.

object
error
required

Human-readable description of what went wrong.

string
Examples
Example limited 
{
  "error": "rate limit exceeded"
}
